    Description

    Performance Considerations

    If your session time zone is set to SYSTEM (the default), FROM_UNIXTIME() will call the OS function to convert the data using the system time zone. At least on Linux, the corresponding function (localtime_r) uses a global mutex inside glibc that can cause contention under high concurrent load.

    Set your time zone to a named time zone to avoid this issue. See mysql time zone tables for details on how to do this.

    -

    Examples

    +
    MariaDB starting with 11.7

    From MariaDB 11.7, FROM_UNIXTIME(0) now returns NULL instead of '1970-01-01 00:00:00' (assuming time_zone='+00:00'). See MDEV-15751.

    InnoDB Temporary Tablespaces

    When the user creates a temporary table using the CREATE TEMPORARY TABLE statement and the engine is set as InnoDB, MariaDB creates a temporary tablespace file. When the table is not compressed, MariaDB writes to a shared temporary tablespace as defined by the innodb_temp_data_file_path system variable. MariaDB does not allow the creation of ROW_FORMAT=COMPRESSED temporary tables. All temporary tables will be uncompressed. MariaDB deletes temporary tablespaces when the server shuts down gracefully and is recreated when it starts again. It cannot be placed on a raw device.

    Internal temporary tablespaces, (that is, temporary tables that cannot be kept in memory) use either Aria or MyISAM, depending on the aria_used_for_temp_tables system variable. You can set the default storage engine for user-created temporary tables using the default_tmp_storage_engine system variable.

    Prior to MariaDB 10.2, temporary tablespaces existed as part of the InnoDB system tablespace or were file-per-table depending on the configuration of the innodb_file_per_table system variable.

    +

    Syntax for the value of the innodb_temp_data_file_path variable

    +

    The options for innodb_temp_data_file_path is one path or a set of paths, separated by ';'.

    +

    The syntax for each path is:

    +
    path:size[:autoextend][:max:size][:autoshrink]
    +

    size can have extensions 'G' (Gigabytes), 'M' (Megabytes) or 'K' (Kilobytes). If no extension is given, then megabytes is assumed.

    +
    • The first size argument is the initial size of the temporary table space. +
    • autoextend means that the file size will automatically increase if needed. +
    • max can be used to limit the total size of the temporary file if autoextend is used. +
    • autoshrink means that the file will shrink to original size when possible. +
    +

    Only the last path can have the autoextend , max and autoshrink options.

    Sizing Temporary Tablespaces

    In order to size temporary tablespaces, use the innodb_temp_data_file_path system variable. This system variable can be specified as a command-line argument to mysqld or it can be specified in a relevant server option group in an option file. For example:

    [mariadb]
     ...
     innodb_temp_data_file_path=ibtmp1:32M:autoextend
    -

    This system variable's syntax is the same as the innodb_data_file_path system variable. That is, a file name, size and option. By default, it writes a 12MB autoextending file to ibtmp1 in the data directory.

    +

    This system variable's syntax is the same as the innodb_data_file_path system variable. That is, a file name, size and option. By default, it writes a 12MB autoextending file to ibtmp1 in the data directory.

    To increase the size of the temporary tablespace, you can add a path to an additional tablespace file to the value of the the innodb_temp_data_file_path system variable. Providing additional paths allows you to spread the temporary tablespace between multiple tablespace files. The last file can have the autoextend attribute, which ensures that you won't run out of space. For example:

    [mariadb]

    Syntax

    SESSION_USER()
     

    Description

    -

    SESSION_USER() is a synonym for USER().

    +

    Prior to MariaDB 11.7, SESSION_USER() is a synonym for USER().

    +

    From MariaDB 11.7, it shows the value of CURRENT_USER() when the session was created, that is, it shows a user@host pair from the mysql.global_priv table, like CURRENT_USER(), but unlike CURRENT_USER() it will not change inside stored routines and views. This is SQL Standard behavior for the SESSION_USER function.

    +

    Backward-compatible behavior can be restored by setting old mode to SESSION_USER_IS_USER.

    ST_IsValid was added in MariaDB 11.7.

    +

    Syntax

    +
    ST_IsValid(g)
    +

    Description

    +

    Given a geometry input, returns 1 if the argument is geometrically valid, 0 if the argument is not geometrically valid.

    +

    Unlike ST_Validate, requires valid GIS data, or ERROR 3037 (22023): Invalid GIS data provided to function st_isvalid is returned.

    +

    Examples

    +
    SELECT ST_IsValid(ST_GeomFromText('LINESTRING (0 0, 1 1)'));
    ++------------------------------------------------------+
    +| ST_IsValid(ST_GeomFromText('LINESTRING (0 0, 1 1)')) |
    ++------------------------------------------------------+
    +|                                                    1 |
    ++------------------------------------------------------+
    +
    +SELECT ST_IsValid(ST_GeomFromText('LINESTRING (0 0, 0 0)'));
    ++------------------------------------------------------+
    +| ST_IsValid(ST_GeomFromText('LINESTRING (0 0, 0 0)')) |

    +|                                                    0 |
    ++------------------------------------------------------+
    +

    A POINT requires both x and y co-ordinates:

    +
    SELECT ST_IsValid(ST_GeomFromText('POINT (0)'));

      Creating a S `te` timestamp(6) GENERATED ALWAYS AS ROW END, PERIOD FOR SYSTEM_TIME (`ts`, `te`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 WITH SYSTEM VERSIONING -

      Inserting Data

      +
      MariaDB starting with 11.7

      From MariaDB 11.7, it is possible to convert a versioned table from implicit to explicit row_start/row_end columns. Note that in order to do any ALTER on a system versioned table, system_versioning_alter_history must be set to KEEP.

      +
      CREATE OR REPLACE TABLE t1 (x INT) WITH SYSTEM VERSIONING;
      +
      +SET system_versioning_alter_history = keep;
      +

      +  ADD COLUMN re TIMESTAMP(6) AS ROW END, ADD PERIOD FOR SYSTEM_TIME (rs,re)
      +
      +

      Prior to MariaDB 11.7, this would result in a duplicate row error:

      +
      CREATE OR REPLACE TABLE t1 (x INT) WITH SYSTEM VERSIONING;
      +
      +SET system_versioning_alter_history = keep;

      +
      +ERROR 4134 (HY000): Duplicate ROW START column `rs`
      +

      Inserting Data

      When data is inserted into a system-versioned table, it is given a row_start value of the current timestamp, and a row_end value of FROM_UNIXTIME(2147483647.999999). The current timestamp can be adjusted by setting the timestamp system variable, for example:

      SELECT NOW();

    Syntax

    USER()
     

    Description

    Returns the current MariaDB user name and host name, given when authenticating to MariaDB, as a string in the utf8 character set.

    -

    Note that the value of USER() may differ from the value of CURRENT_USER(), which is the user used to authenticate the current client. -CURRENT_ROLE() returns the current active role.

    -

    SYSTEM_USER() and SESSION_USER are synonyms for USER().

    +

    Note that the value of USER() may differ from the value of CURRENT_USER(), which is the user used to authenticate the current client. CURRENT_ROLE() returns the current active role.

    +

    SYSTEM_USER() and, prior to MariaDB 11.7, SESSION_USER, are synonyms for USER().

    Statements using the USER() function or one of its synonyms are not safe for statement level replication.
